Sienna Miller has revealed that she was approached about appearing on The Celebrity Traitors, but the timing clashed with the arrival of her third child.
The actress said she was interested in participating in the show, but she would have been giving birth around the time filming was scheduled to take place.
Sienna Miller was approached for The Traitors after expressing interest but passed because she was pregnant
Speaking on SiriusXM’s Radio Andy show The Julia Cunningham Show, Miller explained that producers had considered her for The Celebrity Traitors. However, the filming schedule coincided with the birth of her third child, making it impossible for her to participate.
“They did try to get me, but I was giving birth the month that they were shooting it,” Miller said. “I said to Nick on set, I was like, ‘Would, do you think they’d have me?’ And he and the producer then said, ‘Yes, but then I would have been in labor.’”
The “Nick” Miller referred to is actor and comedian Nick Mohammed, her co-star in the upcoming legal drama War. Mohammed previously appeared on The Celebrity Traitors and reached the final during the first celebrity season in 2025.
The filming dates ultimately made the opportunity impractical for Miller. Production began in 2026 and took place in the Scottish Highlands. Meanwhile, the filming was scheduled around April and May at Ardross Castle. The 21-person cast includes celebrities such as Michael Sheen, Richard E. Grant, Maya Jama and James Blunt.
Miller welcomed her third child, her second with fiancé Oli Green, in May 2026. She also shares daughter Marlowe with her former partner, Tom Sturridge. Miller and Green confirmed their engagement in June after dating since 2021.
The actress has previously spoken candidly about balancing her career and motherhood. Miller spoke to British Vogue about having a third child at 40. She also talked about how motherhood had changed her perspective on life. She also discussed how parenthood fits into her life alongside her career.
Meanwhile, The Celebrity Traitors is set to return for its second season on BBC One and BBC iPlayer on October 1, 2026.
